Following the procedure that is described in the http://wiki.openwrt.org/doc/howto/extroot

I had to mount a filesystem in which the overlay will be copied to.

I am using a Verbatim Store 'n' Stay Nano USB Drive - 8GB , (FAT32 filesystem)

and I have to configure OpenWRT to recognize this device.

I have installed the following additional packages :

kmod-usb-storage, kmod-fs-vfat , block-mount.

After rebooting and plug-ing the USB, I had the interface in /dev/sda and /dev/sda1 and the web page of the router seemed like this:

http://wiki.openwrt.org/doc/recipes/usb-storage-samba-webinterface

Next step was to mount, I followed the instructions as described in the http://wiki.openwrt.org/doc/howto/usb.storage

mkdir -p /mnt/share
mount -t vfat /dev/sda1 /mnt/share -o rw,sync

But I received an error mount: mounting /dev/sda1 on /mnt/usb failed: Invalid argument. I have searched a bit around web to find any solution but it seems that sth is missing.

Have you encountered a similar problem with OpenWRT on TP-LINK(3040)?

Thanks in advance,

Theodoros
